Abstract

The compact disc player includes an opposed pair of panel form loudspeakers which are attached to it. Each loudspeaker includes a distributed mode acoustic radiator with a transducer mounted on it. The transducer vibrates, causing the radiator to resonate. A body portion has a turntable with a lid, which closes over the turntable. The loudspeakers are mounted on the lid. The speakers may be hinged on the lid or housed in a slot, so as to slide from a stored position. Each radiator includes a stiff lightweight panel which has a cellular core, sandwiched by opposed skin layers.
